(Deister) Germany Lauenau Application December 30, 1932, Serial No.649,669 In Germany December 31, 1931 2 Claims The present inventionrelates to a frame for chairs, tables or the like. 1

Such frames are known in which the corners of the frames are providedwith Wooden blocks or Special screw connections and metal pins whichmust be connected with the legs of the frame are also known.

Contrary to all such known kinds of corner connections, the presentinvention produces a positive stiffening of the whole chair or tableframe without the use of any kind of pegs, peg holes, screw connections,metal pins, metal angles, corner blocks and the like. This result isaccomplished by securing to each of the inner side surfaces of the rimor border frame two ledges or bars which are separated from each otherby intermediate spaces, the ends of these bars pressing strongly againstthe inner upper side sur-' faces of the legs. A bottom plate which issolidly connected with the lower bars has corner cut outs which solidlysurround the edges of the legs and press the legs against the corners ofthe border frame; By this means, all rails and bar connections below theborder frame, or at the lower ends of the legs, where they are ofteninconvenient, and are objectionable places for the deposition of dust,may be dispensed with.

Furthermore, all parts directly abut with an unweakened cross sectionsquarely against each other without tenons, dowels, screws or the like,so that the many places where breakage may occur, which are produced inknown frames by tenons, mortises and the like, are done away with by theobject of the invention.

The invention is more particularly described with reference to theaccompanying drawing, in which:

Figure l is a vertical section through a frame Figure 2 a correspondinghorizontal section, and

Figure 3 an inside perspective view of a corner of the frame.

The chair or table-frame according to the invention consists of theborder frame a, the legs 12 standing at the inner angles of the borderframe,

the bars 0 and d placed between the legs, which press the legs firmlyagainst the border frame and against one another; and the plate e firmlyenclosing the border frame and legs and effectively protecting the.frame against diagonal distortion or warping (see direction of arrows).

By the arrangement of all the connections and stiffening members--bars cand d and plate ein the border frame a, and the avoidance of any tenonsand mortises on the legs and points of connection the frame isunbreakable.

Having now particularly described the nature of my said invention and inwhat manner the same is to be performed, I declare that what I claimis 1. Furniture structure of the class described comprising an outerrectangular frame, a leg mounted in each inside corner of the frame,four upper spreader bars extending along the upper portion of the innersides of the frame and between the upper ends of the legs, four lowerspreader bars spaced below the upper spreader bars and extending alongthe lower portion of the inner sides of the frame and between lowerportions of the legs, said upper and lower spreader bars pressing thelegs firmly against the inside corners of the frame, and a bottom platesecured below the lower spreader bars and closing the lower portion ofthe frame, said bottom plate having its corners cut out to receive andpress against'the legs, whereby diagonal distortion or Warping of theframe is prevented.

2. Furniture structure of the class described comprising an outerrectangular frame, a leg mounted in each inside corner of the frame,four upper spreader bars extending along the upper portion of the innersides of the frame and between the upper ends of the legs, four lowerspreader bars spaced below the upper spreader bars and extending alongthe lower portion of the inner sides of the frame and between lowerportions of the legs, said upper and lower spreader bars pressing thelegs firmly against the inside corners of the frame.
